GENERAL DESCRIPTION
The ADG1204 is a complementary metal-oxide semiconductor
(CMOS) analog multiplexer, comprising four single channels
designed on an iCMOS (industrial CMOS) process. iCMOS® is
a modular manufacturing process that combines high voltage
CMOS and bipolar technologies. It enables the development of
a wide range of high performance analog ICs capable of 33 V
operation in a footprint that no previous generation of high
voltage parts has been able to achieve. Unlike analog ICs using
conventional CMOS processes, iCMOS components can tolerate
high supply voltages while providing increased performance,
dramatically lower power consumption, and reduced package size.
The ultralow capacitance and charge injection of this multiplexer
makes it an ideal solution for data acquisition and sample-and-
hold applications, where low glitch and fast settling are required.
Fast switching speed coupled with high signal bandwidth makes
the part suitable for video signal switching. iCMOS construction
ensures ultralow power dissipation, making the part ideally
suited for portable and battery-powered instruments.

The ADG1204 switches one of four inputs to a common output,
D, as determined by the 3-bit binary address lines: A0, A1, and
EN. Logic 0 on the EN pin disables the device. Each switch
conducts equally well in both directions when on and has an
input signal range that extends to the supplies. In the off condi-
tion, signal levels up to the supplies are blocked. All switches
exhibit break-before-make switching action.
